I've been a journalist now since I was about 17, and it's an interesting industry to be in at the moment, because as you all know, there's a huge amount of upheaval going on in media, and most of you probably know this from the business angle, which is that the business model is pretty screwed, and as my grandfather would say, the profits have all been gobbled up by Google.

So it's a really interesting time to be a journalist, but the upheaval that I'm interested in is not on the output side. It's on the input side. It's concern with how we get information and how we gather the news. And that's changed, because we've had a huge shift in the balance of power from the news organizations to the audience. And the audience for such a long time was in a position where they didn't have any way of affecting news or making any change. They couldn't really connect. And that's changed irrevocably.

My first connection with the news media was in 1984, the BBC had a one-day strike. I wasn't happy. I was angry. I couldn't see my cartoons. So I wrote a letter. And it's a very effective way of ending your hate mail: "Love Markham, Aged 4." Still works. I'm not sure if I had any impact on the one-day strike, but what I do know is that it took them three weeks to get back to me. And that was the round journey. It took that long for anyone to have any impact and get some feedback. And that's changed now because, as journalists, we interact in real time. We're not in a position where the audience is reacting to news. We're reacting to the audience, and we're actually relying on them. They're helping us find the news. They're helping us figure out what is the best angle to take and what is the stuff that they want to hear. So it's a real-time thing. It's much quicker. It's happening on a constant basis, and the journalist is always playing catch up.

To give an example of how we rely on the audience, on the 5th of September in Costa Rica, an earthquake hit. It was a 7.6 magnitude. It was fairly big. And 60 seconds is the amount of time it took for it to travel 250 kilometers to Managua. So the ground shook in Managua 60 seconds after it hit the epicenter. Thirty seconds later, the first message went onto Twitter, and this was someone saying "temblor," which means earthquake. So 60 seconds was how long it took for the physical earthquake to travel. Thirty seconds later news of that earthquake had traveled all around the world, instantly. Everyone in the world, hypothetically, had the potential to know that an earthquake was happening in Managua. And that happened because this one person had a documentary instinct, which was to post a status update, which is what we all do now, so if something happens, we put our status update, or we post a photo, we post a video, and it all goes up into the cloud in a constant stream.

And what that means is just constant, huge volumes of data going up. It's actually staggering. When you look at the numbers, every minute there are 72 more hours of video on YouTube. So that's, every second, more than an hour of video gets uploaded. And in photos, Instagram, 58 photos are uploaded to Instagram a second. More than three and a half thousand photos go up onto Facebook. So by the time I'm finished talking here, there'll be 864 more hours of video on Youtube than there were when I started, and two and a half million more photos on Facebook and Instagram than when I started.

So it's an interesting position to be in as a journalist, because we should have access to everything.
